WILLIAM F. ECKERT AND WILLIAM C. WHITCOMB, OF ROCHELLE, ILLINOIS.

MINE-LOCOMOTIVE.

- and IVILLIAM C. VHITcoMB, citizens of the United States, and residents of Rochelle, county of Ogle, and State of Illinois, have invented certain new and useful Improvements in Mine-Locomotives, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to explosive engines, and more particularly to those used upon locomotives.

The object of the invention is to provide improved means for cooling the cylinders of an explosive engine; and the invention contemplates a water-cooling and circulating system especially adapted for use upon locomotives intended to run in mines or other places where clean water is not read- The construction also provides that all of the exposed parts of a locomotive may be of stout and durable construction.

power cylinders, as 15, 16, each having a chambered wall 17 for receiving a cooling fluid.

The power shaft of the engine 14 is shown at 18. This power shaft is most conveniently located upon the median line of the locomotive frame 10, and the power cylinders, as 15, 16, yare preferably arranged 1n groups upon opposite sides of the power shaft. /Vater for cooling the power cylinders of the engine vis delivered to the wall chamber 17 of each of the cylinders 15 and 16, through a pipe, as 19 and 20. Preferably both of the pipes 19, 20, branch, as at 21 (Figs. l and 2) from a common supply pipe 22. This supply pipe is shown as leading from a rotary circulating pump 23 located adjacent the front end of the locomotive frame. A bracket 24 is provided for supporting the circulating pump 23 in a convenient position. As shown, the bracket 24 is formed upon the front end wall 25 of a housing or case 2G, which incloses certain of the operative parts of the locomotive which pertainto the transmissionof power from the engine shaft 13 to the wheels of the frame 10 and include intermeshing bevel gears 70, 71, and speed-reducing gears 72, 73. The bevel gear 70 is mounted directly upon the power shaftI 18. The gear 73 transmits power to the wheels of the locomotive 'frame through sprocket chains 74,75.

In the operation of the device, the circu- .lating pump 23 draws water from a reser` voir and delivers it to the wall chambers 17 of the power cylinders, as 15, 16, through the main supply pipe 22 and branch pipes 19, 20. The water is then delivered to spray boxes 29 and 30, where it is cooled, and from there it is returned to the reservoir. The reservoir is shown in the drawings at 27. It is conveniently located within the end sill or bumper 13 ofthe locomotive frame, this bumper, as shown, being formed as an integral chambered casting including the reservoir. A pipe 28 leads upwardly from the foot of the reservoir 27 through its to-p to the intake side of the circulating pump 23.

The two spray boxes 29 and 30 are of similar construction, but they are of complementary shape for disposition, respectively, upon the right and left hand lsides of the locomotive frame. As shown in Figs. 1, 2, 3, 4 and 8 of the drawings, each of the spray boxes comprises an oblong rectangular Chamb-ered casing located upon one of the side sills, as 11, 12, of the locomotive frame. The top of this casing is formed double, as indicated at 77, 78 (Figs. 3 and 4) and provides a water passage 31 therein. Provision is preferably made for forcing air through the main body 7 G of the chamber of the casing from end to end. A fan 32 is most desirably employed for forcing air through the spray boxes. This fan is shown as being located immediately in front of the engine 14. It may be of any well known form of construction, and preferably includes a rotary blade 33, rigidly mounted upon the power sln ft 1S and inclosed by a case 34, having discharge orifices, as 35, 36, adjacent its periphery. Each of the discharge orifices 35, 3G, of the fan case is connected to the main chamber 7G of one of the spray boxes 29, 30, by means of a tubular elbow, as 37, 38. Outlets for the escape of air delivered to the spray boxes by the fan are provided at that end remote from the connecting` elbows 37, 38, in a screened laterally-directed aperture, as 39, 40, one of which is clearly shown in Fig. 1 of the drawings. Preferably suitable battles, as 4l, 42, are provided within the main chamber 76 of each of the spray boxes adjacent the air outlet opening, as 39, 40.

A plurality of spray nozzles, 43, one of which is shown in detail in Fig. 5 of the drawings, are provided for dischargingwater from the passage 31 of each of the spray boxes into the main chamber 7G thereof, in the form of a` spray. For returning this water to the reservoir `27, a connecting elbow pipe, as 44, 45, unites the forward end of each spray box with the top of the reservoir. Each of the spray nozzles 43 is so constructed and secured in place that it may be separately removed for inspection or adjustment. As shown, the upper and lower walls 77, 78, of each of the water passages 31 are provided with a plurality of registering apertures, as 46, 47 (Fig. 4). The apertures, as 4G, formed in the upper wall 77 of the passages are preferably threaded, while those, as i7, formed in the lower wall 78 preferably have smooth margins. The rear end portion 48 of each of the spray nozzles 43 is threaded for engagement with one of thel threaded apertures 4G, while the forward end portion, as 49, of each spray nozzle has a close sliding fit in the corresponding aperture 47.

W'hen in place, each of the spray nozzles 43 is surrounded intermediate its ends by water contained in the corresponding water passage 31. ln order that these nozzles may serve to discharge this water into the main chamber 7 6 of spray boxes to be engaged and cooled by air from the fan 32, each of t-he spray nozzles has a discharge orifice 51 upon its inner or forward end, and laterally-opening induction ports 52, the outer or rear end of the nozzle being closed. For regulating the discharge from the spray nozzles, each is provided with an adjusting screw 53, which enters the spray nozzle from its inner end and has a flaring head 53a. The flaring head 53n of the adjusting screw 53 coperates with the mouth of the orifice 51 to discharge water received in the water passage 31 into the main chamber 76 of the corresponding spray box in the form of a fan-like spray, the character of the spray and the quantity of water delivered being determined by adjustment of the screw. Access to the adjusting screw 53 for regulating it and for cleaning the spray nozzle may be readily had by removing the nozzle. For this purpose each of the nozzles is provided with a wrench-receiving socket 50 at its rear end. Preferably the water passage 31 of each of the spray boxes 29, 30, is connected at one end to the wall chamber 17 of one of the power cylinders, as 15, 1G, of the engine 14, by a pipe, as 54, 55.

The circulating pump 23 is conveniently driven from the power shaft 18 of the locomotive engine 14. As shown, a countershaft 56 is provided. This countershaft is journaled in the walls of the casing 2G and projects through the end wall 25 thereof for connection with the pump. Intermeshing gears 57, 58 (Figs. 1 and 2), mounted, respectively, on the power shaft 18 and on the countershaft 56 adjacent the rear end of the latter, provide for the continuous operation of the pump whenever the engine 14 is in service.

Figs. G and 7 of the drawings illust-rate a form of spray box 59 which may be employed in lieu of those designated 29 and 30. The spray box 59 is provided with nipples 60 and 61, for connect-ion, respectively, with one of the pipes, as 55, leading from the wall chamber of one of the engine cylinders, as 1G, and with one of the return connections, as 45, to the reservoir 27. This spray box is also provided with an air inlet port 62 for connection with one of the elbows, as 37, leading from the fan The nipple 60 communicates wit-h a water passage 63 formed in the cover plate 64 of the spray box 59. The cover plate G4 is removable, and is normally held in place by bolts, as 65, 66. The upper and lower walls, as 79, 80, of the cover plate 64 are provided with a plurality of registering apertures 67, 68, similar to the apertures 4G, 47 provided in the upper and lower walls 77, 78, of the water passages 31 of the spray boxes 29 and 30. These apertures may be fitted with removable spray nozzles 69, videntical in construction with those shown at 43.

With the form of construction illustrated in Figs. 6 and 7 any one of the spray nozzles 69 may be removed independently of the others for adjustment and cleaning, or access to the entire set of spray nozzles and to the interior of the main chamber 69 of the spray box, may be had by removing the cover plate 64.
